Abstract: 1286742 Composting PORTLAND-ZEMENTWERKE HEIDELBERG AG 24 Feb 1970 [3 April 1969] 8841/70 Heading C1B In a composting process, humid crude compost material (particularly a mixture of 75% domestic refuse and 25% clarification sludge) which has been broken down, e.g. to 40 mm pieces, is subjected to an intensive kneading action, e.g. by a kneading machine known from the rubber, plastics, dough preparation or clay processing industry, so as to break up and disintegrate paper and foil scraps, before the composting. Hygienization, i.e. the destruction of pathogenic bacteria, and ripening of the compost is carried out by passing air through the compost, either by blowing or by suction, the air being fed in as cadenced surges interrupted by rest periods of 10-60 minutes, the length of the rest periods being such that the oxygen content of the waste gas does not fall below 10%. If this occurs, anaerobic processes begin to develop. The required humidity of the compost may be maintained by spraying. More rapid ripening of the compost is obtained by this method than by previous methods.

Abstract: 1499033 Aerials KIEV POLITEKHNICHE INST IM 50-LETIA VELIKOI OKTYABR SOTSIALISTICHE REVOL JUT 4 March 1975 8977/75 Heading H4A An aerial comprises a piezoelectric element 1, the element having first 4 and second 5 sections acoustically coupled together the first section 4 being connected to a transmission line 8 and the second section 5 radiating or receiving e.m. waves into or from free space. Different elements can be constructed to cover the frequency range 10<SP>2</SP>-10<SP>7</SP> Hz. As shown in Fig. 1 the section 4 is connected to the transmission line 8 by leads from electrodes 6 and terminals 7 in the insulating housing 2. The second section 5 may also carry an electrode 9 which may be connected to a layer of foil 15 spread on the housing surface. As shown in Fig. 2, the element 1 may be composed of two acoustically coupled layers 10. The mode of vibration of the element is governed by the selection of polarization directions (indicated as arrows) relative to the electrodes 6. The aerial efficiency is increased by the introduction of a symmetrically disposed third section 5<SP>1</SP>, by using a ring form for electrodes 6 (not shown), by composing at least the sections 5, 5' from acoustically coupled half-wave units (Figs. 4, 6, not shown) and by using materials of differing electrical and acoustical impedances for sections 4 and 5. The operating frequency can be lowered by loading (12, Fig. 3, not shown) with a body of relative permitivity less than 100 and by attaching the element 1 to a support (11). In the last case, mechanically compensating elements (16, Fig. 8, not shown) may be disposed on the support. In another embodiment (Fig. 9, not shown) the selectivity and bandwidth are increased by using two piezoelements with different operating frequencies. The use of more than one element imparts directivity to the aerial. The elements 1 may be clamped at nodes (not shown) or held in place by rubber packing 3. The elements may be discs (Fig. 5, not shown) or cylinders (Fig. 4, not shown).

Abstract: 1275751 Fluid logic and switching circuit JOSEPH LUCAS (INDUSTRIES) Ltd 20 May 1969 [26 Feb 1968] 9134/68 Heading F1P A fluidic control circuit comprises a bi-stable input stage 10, an intermediate chamber 21 and an output stage vortex chamber 28, the circuit controlling the output when the pressure ratio P 1  /P 2  reaches a certain value. The pressures P 1  and P 2  can be the compressor delivery pressure and intermediate pressure respectively of a gas turbine engine, and P o  is atmospheric pressure. The tube 16 is fed with a proportion of the pressure P 1 , and when pressure P 2  is greater than the proportional pressure a flow is directed into the chamber 21 where the pressure is increased and transmitted through outlet 30 to the chamber 28. A flow from inlet 31 is swirled in a vortex about outlet 27 by the pressure from outlet 30 and a reduced fluid-flow passes through outlet 27, the outlet flow 27 varying inversely as the flow from outlet 30. When the pressure ratio P 1  /P 2  reaches its predetermined ratio flow input stage 10 is directed to pipe 13, the pressure in chamber 21 falls, the vortex in chamber 28 is insufficient for a vortex, and fluid-flows direct from inlet 31 to the outlet 27. In a modification Fig. 2 (not shown) the chamber 21 is replaced by an ejector and in Fig. 3 (not shown) the vortex chamber is modified and air used as fluid.
